Week 4: Programming Assignment 1

Due on 2024-08-22, 23:59 IST

Create a Python program that identifies the presence of a "saddle point" in a given matrix. A saddle point is defined as an element in the matrix that is the smallest in its row and the largest in its column. The matrix is represented as a nested list, where each nested list corresponds to a row of the matrix. The program should determine if at least one saddle point exists in the matrix. If a saddle point is found, the program/function should print 1; otherwise, it should print 0.

Input Format:
The first input is an integer r , the number of rows in the matrix.
The second input is an integer c, the number of columns in the matrix.
The next r lines each contain c integers, representing the elements of each row of the matrix.

Output Format:
The output is 1 if a saddle point exists, otherwise 0.


Example:

Input:

3
3
2 0 3
2 1 4
4 2 6

Output:
1

Reason:
Element 2 in third row and second column is minimum in its row and maximum in its column.
So, it is a saddle point.

The second input is an integer 𝑐 , the number of columns in the matrix.
The next 𝑟 lines each contain 𝑐 integers, representing the elements of the matrix.
The final input is an integer 𝑠, representing the scalar value.

Output Format:
The output consists of 𝑐 lines, each containing 𝑟 integers, representing the elements of the resulting matrix after multiplying the transpose of the original matrix by the scalar.

Create a Python program that finds the k-th largest and k-th smallest elements in a list of integers. The program should prompt the user to input a list of integers and a value `k`. The program should then find and print:

• 1 if the k-th largest and k-th smallest elements are the same and are at the middle of the sorted list.
•  -1 if the k-th largest and k-th smallest elements are the same but are not in the middle of the sorted list.
• 0 if the k-th largest and k-th smallest elements are different.

Input Format:

• The first line of input consists of a space-separated list of integers.
• The second line of input consists of a single integer k.

Output Format:

The output consists of a single integer 1, -1, or 0 based on the conditions specified.

Example:

Input:

3 8 7 5 9 1

Week 7: Programming Assignment 1

Due on 2024-09-12, 23:59 IST

Question
You are given a board game scenario with ladders and snakes. A player starts at a given position on the board, and you are provided with the result of a die roll. You need to determine whether the player lands on a ladder, a snake, or a normal block after moving.

Write a Python function named move_player that takes four inputs:

• A list ladders containing the indices of blocks with ladders.
• A list snakes containing the indices of blocks with snakes.
• An integer current_position representing the player's current position on the board.
• An integer die_roll representing the result of a die roll.

The function should return:

• 1 if the player lands on a block with a ladder,
• -1 if the player lands on a block with a snake,
• 0 if the player lands on a block with neither.
  

Take necessary inputs, pass the inputs to the function, and print the return value of the function.

Input Format
The input consists of four lines:

1. The first line contains space-separated integers representing the ladder indices.
2. The second line contains space-separated integers representing the snake indices.
3. The third line contains a single integer representing the current position of the player.
4. The fourth line contains a single integer representing the die roll result.

Output Format
The output consists of a single integer (1, -1, or 0) as per the conditions mentioned above.

Due on 2024-09-12, 23:59 IST

Question

Write a Python program that takes a matrix of size r x c as input, where r is the number of rows and c is the number of columns. The program should check if the matrix is binary (i.e., all elements are either 0 or 1) and if it is symmetric (i.e., the matrix is equal to its transpose).

The program should output:

• 11 if the matrix is both binary and symmetric,
• 10 if the matrix is binary but not symmetric,
• 01 if the matrix is not binary but symmetric,
• 00 if the matrix is neither binary nor symmetric.

Input Format:

• The first line contains an integer r representing the number of rows.
• The second line contains an integer c representing the number of columns.
• The next r lines each contain c space-separated integers representing the elements of the matrix.

Output Format:

• The output consists of a single string (either 11, 10, 01, or 00) as per the conditions mentioned above.

Example:

Input:
3

Question:

Write a recursive function named collatz that accepts a positive integer n as an argument, where 1 < n ≤ 32,000, and returns the number of times the Collatz function has to be applied repeatedly in order to first reach 1.

The Collatz function is defined as follows:

• If n is even, divide n by 2.
• If n is odd, multiply n by 3 and add 1.

The function should continue applying this process until n becomes 1, and return the number of steps taken.

Input Format:

A single integer n where 1 < n ≤ 32,000.

Output Format:

A single integer representing the number of steps required for n to reach 1.

Question:
There are `n` people who start in a happy state. The following rules determine how people move between states after each iteration:

- A person in the happy state has a 70% chance of moving to a sad state, and a 30% chance of staying in the happy state.
- A person in the sad state has a 50% chance of moving to a happy state, and a 50% chance of staying in the sad state.

Write a program that computes the number of people in the happy and sad states after 3 iterations.

Input Format:
A single integer `n` representing the number of people who start in the happy state.

Output Format:
Two integers separated by a space, where the first integer is the number of people in the happy state and the second is the number of people in the sad state after the 3rd iteration.
